Does accent matter?

I believe what more important is to get your message across properly and comfortably, instead of painstakingly speaking with accents but lacking in the accuracy department. Many people are trying hard to speak with accents, especially American and British accents. But what many of us don't know is that some accents that these people try to emulate are regarded as the accents of those from the lower social class in foreign cultures. Thus, my advice is, don't attempt to do something that you're unsure of; it might lead you to embarrassment.

If you're confused, just speak proper English, doesn't matter if it sounds very Malaysian-ish, because that shows your national identity. 

Here's sharing an interesting video for you who would like to learn accents, just for fun. Enjoy :)
